The deskew and orientation detection work in a different way than other recognition modules. The working of both operations can be adjusted through functions IG_REC_asian_deskew_enabled_get/IG_REC_asian_deskew_enabled_set and IG_REC_asian_orientation_enabled_get/IG_REC_asian_orientation_enabled_set. If these settings are FALSE, the AUTO methods (IG_REC_IMG_DESKEW_AUTO, IG_REC_IMG_ROTATE_AUTO) of these operations for Asian OCR are equal to the case when they are switched off (IG_REC_IMG_DESKEW_NO, IG_REC_IMG_ROTATE_NO). If the settings are TRUE, or the deskew and orientation are not set to AUTO, the working of these methods is the same for both the Asian and the Western cases.
